Step 1

Preheat oven to 180°C (350°F) and fold a 15 cm x 15 cm (7 inch x 7 inch) brownie pan with parchment paper.

Step 2

In a large bowl, mash the bananas and combine with the egg until you get a smooth mixture.

Step 3

Add protein powder, cocoa powder, coconut flour and a pinch of salt, then mix well until you get a smooth brownie batter. Depending on the type of protein powder used, you may need to add as much as 80 ml (1/3 cup) of milk : start with 1 to 2 tbsp and add as much milk as required to get a smooth batter.

Step 4

Transfer the banana protein brownie batter to the prepared brownie pan, then bake in hot oven for 20 to 25 minutes Let cool completely at room temperature before slicing.
